Fogstar Energy FS4000 18650 4000mAh Battery

The Fogstar Energy 4000mAh 18650 battery (Dark Blue) is the perfect upgrade for vapers who are tired of constantly charging their device. With a huge 4000mAh capacity, it holds much more energy than a standard vape battery, meaning your kit stays powered up for significantly longer.

This battery is designed specifically for low-power vaping (Mouth-to-Lung). It has a 10A discharge limit, which means it works best when your device is set to lower wattages (typically between 10W and 20W). If you use a standard box mod but prefer a gentle, cigarette-style draw with a higher resistance coil, this battery is the ideal partner.

Please note: Because of the 10A limit, this battery is not suitable for high-power sub-ohm vaping. Using it at high wattages will drain it too quickly or cause your device to show a safety error. But for everyday, low-power use, it is a champion of endurance.
